<body class='hmmessage'><div dir='ltr'>Thanks everybody. While I am trying to digest all the responses, I am here to reply why we are not considering a driver. We already have an application which listens to neutron events to do some other stuff, it might just be easier for us if we reuse this framework and program the LBaasS from there. If we use driver, there is this added efforts where we need to ask the user to install our driver, modify the conf file, start the agent and restart neutron. We might still go back to driver/agent later because it seemed that it helps scale better. <div><br></div><div>Thanks Doug, Kevin, Brandon and Kunal! You guys are so helpful.

<div class="ecxhmmessage"><div dir="ltr">Is there a way to add an LBaaS service without having to use neutron plugin/agent framework?<div><br></div><div style="text-align:left;">I want to add a LBaaS service without an LBaaS agent running and still want to have lb cli and horizon. When the user configure loadbalance via cli or horizon, neutron will send the events(pool, member, vip create/delete event)in the notification info queue and our application will listen to the queue and program the LBaaS box. So far, I have tried to enable the built-in HAProxy LBaaS(enable the service_plugin to be LoadBalancerPlugin and service provider to be haproxy). By doing that , horizon and cli are all enabled and our application can successfully program LBaaS box using the notification events. The problem with that is that there is a haproxy agent running in the background although we are not using its function. But if I don't enable the agent, we can not use horizon. Currently we don't want to write a LBaaS agent of our own. Is there a way to not to use LBaaS agent and still be able to use horizon/cli to configure loadbalance? During openstack summit at vancouver, I saw paypal loadbalance presentation, they use two providers, one is agent , the other is agentless controller, not sure how that controller works, could not find it through googling.</div><div style="text-align:left;"><br></div><div style="text-align:left;">Regards</div><div style="text-align:left;">Wanjing Xu</div><div><br></div><div><br></div> </div></div>
